It's only chapter 8 trust me I have everything planned out I have notes on this whole story. They both have their own problems and things aren't going to be a "fairy tail" like romance with them. It's the zombie apocalypse, no relationship would be like a fairytale. They've both lost their families and it's going to affect them in different ways. Chapter 8 was just the beginning of where we see kind of a resolution in there differences. If you caught my season 3 reference in the last chapter ("I don't take chances anymore") you see Carl is like his dad in a sense to where he doesn't take his chances with the living. Carl has the fight the dead, fear the living mentality at this point. I'm working on chapter 9 right now, and it'll all be more clear as the story progresses. Just hang with me :)
